Recently, I see many social apps which can capture and save video from both cameras at the same time. I can show my surroundings using the back camera and in a small PIP layout, I can see myself.
What needs to be done to accomplish this?
Can we record with both cameras at the same time and use ffmpeg to combine 2 videos?
Can we use image streams from both cameras at the same time to overlay them on each other?
